Closed-Loop Recyclable Fluoro-Containing Graft Copolymers This cover illustrates a closed-loop recyclable fluoropolymer constructed by PVDF-CTFE backbones and PTMC side chains. The graft copolymer serves as a high-performance battery electrolyte with enhanced ionic conductivity and mechanical robustness. Selective deconstruction of PTMC side chains yields a recycled backbone for capacitor/coating applications, exhibiting high dielectric constant and extreme-environment resistance. The reconstruction process demonstrates dual-life utilization of fluoropolymer—transforming persistent PFAS waste into versatile materials while mitigating environmental impact.
